X Y Z target selectors dont work in minecraft Bedrock

Im making a command block creation that uses the x,y,z target selectors, but I have noticed that they do not work, I used the command /testfor @e[x=1000,y=10,z=1000] this command recognized me even though I wasn't at those coordinates, this happens on all commands that uses the x,y or z target selectors, I dont know whats happening but please fix this, I attached pictures below
